SHEETING ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming' part of Letters Patent N o. 692,124, dated January 28, `1902.

Application and Juiylz, 1901.

T0 all whom iv' may concern: A g

Be it known that we, MIcHAEL ANDREW DROITGOUR, of Pittsburg, in the county of Allegheny and State of Pennsylvania, and GUsTAv F. KALKHOFF, of the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, citizens of the United States of America, have invented a new and Improved Sheeting Attachment for Printing-Presses, of which the following is a full, clear, and exact description. y

The invention relatesto delivery mechanisms of printing-presses; and its object is to provide a new and improved sheetingattachment arranged to' take the printed sheets from the printing-press and wind the same up in an apron or web without one sheet touching or osetting on the other, to allow the sheets to dry properly, and to prevent soiling of the same, as too frequently occurs when piling the sheets by the fly upon the fly-table. The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter,and then pointed out in the claims. A practical embodiment of our invention-is represented in the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the views. Figure l is a side elevation of the improvement as applied. Fig. 2 is a reduced sectional side elevation of the same, the section being on the line 2 2 of Fig. 3; and Fig. 3 is a plan view of the same. i A pair of rollers A are journaled on arms A', secured to a transverse shaft A2, journaledr in" bearings carried by a block B', held on the rear end of the fly-table B, located at the rear end of a cylinder printing-press of any approved construction,so thatwhen the printingpress successively delivers the printed sheets O the latter are engaged on the top at the sides by the said rollers Ato deliver the sheets successively upon the extended portion F of an apron or web F, unwinding from a roll F2 and winding up as a roll F3, as is plainly shown in the drawings. The prin ted sheet isrun down on tapes which extend from the impression.- cylinder to the fly-board, and after the sheet is at rest the rollers A (worked by the action of the fly-rod) drop on thesheet, which is then Serial No. 67,979. (No model.)

caused to travel in the direction the apron is moving and at the same speed. The apron in its passage from the roll F2 to the roll F3 passes around the feed-rollers G G', which, with the roll F3, are driven in unison with the printing-press to give the apron F the desired and necessary traveling speed, so that the apron F takes the sheets with the ends spaced apart and winds up the sheets on the formation of the roll, with the sheets extending between successive layers orconvolutions of the roll The apron F after leaving the feed- :roller G passes around the guide-roller H, journaled in the block B' and located below the rollers A` (see Fig. 2) to cause the sheet O to readily pass onto the extended portion F' of the apron F previous to rolling the sheets up inthe roll F3. The extended portion F' passes over ya guide-roller H' between the roller H and the `roll F2.

The shafts F4 -F5 of the rolls F2 F3 and the shafts G2 G3 of the rollers G' G are journaled in suitable bearings on the frame I of the sheeting attachment, and 'on the said frame' is journaled a shaft J, carrying a pulley J', connected by a belt J2 with a pulley onthe fly-Wheel shaft of the printing-press, so'that y a rotary motion is given to the shaft .I invunison with the printing-press.

i On the shaft J `is secured abevel gear-wheel K, in mesh with a bevel gear-wheel K', secured on the lower end of a vertically-disposed shaft K2, journaledinsuitable bearings on the frame I and carrying at its upper end i afbev'el gear-wheel K2, in mesh with a bevel gear-wheelKl, journaled in the frame I and carrying a spur-wheel L, in mesh with a gearwheel L', Vsecured on the shaft F4 of the roll F3;V `The gear-wheel L' is in mesh with an intermediate` gear-wheel L2,in mesh with a gearwheelN on the shaft G2, and the latter is geared* to the shaft G3 by the gear-wheels N' and N 2as is plainly indicated in Figs. 2 and Now when the shaft .I is rotated rotary motion is given to the shaft K2, and the latter by the gear-wheel described rotates the roll F3 and the feed-rollers G and G' to cause the web. or apron F to travel in the direction of the arrow a, to unwind from the roll F2, and to wind up on the roll F3.

A suitable friction device P (see Fig. 3) is IOC applied to the shaft F5 to prevent the apron F from unwinding too fast from the roll F2. Both shafts F4 F5 are removably held in the frame I to allow of readily removing the shafts for slipping a new apron-roll onto the shaft F4 and for removing the shaft F5 and the roll F3 to another machine for unwinding the apron and freeing the sheets.

Now from the foregoing it is evident that the printed sheets from the printing-press are successively delivered to the extended portion F' of the apron to be then wound up between adjacent layers or convolutions of the roll F3, so that the sheets do not touch each other, and consequently do not set off, as is so frequently the case when piling sheets by the usual ily on the iiy-board.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A sheeting attachment for printingpresses, comprising a traveling apron provided with an extended portion for successively receiving the sheets from the printingpress, the apron being arranged for winding up in a roll with the sheets separated from each other and extending between successive layers of the roll, as set forth.

2. A sheeting attachment for printingpresses, comprising a traveling apron unwinding from a roll and winding up on a roll, means for extending the apron between the unwinding and winding-up rolls,the extended apron part being arranged at the rear of the printing-press and adapted to successively receive the printed sheets, as set forth.

3. A sheeting attachment for printingpresses, comprising a delivering-apron unwinding from a roll and winding up on a roll, means for extending the apron between the unwinding and winding-up rolls, the extended portion of the apron projecting over the rear end of the ily-table of the press, and a feed driven in unison with the press, for contin ually feeding the apron and winding it up into a roll with the sheets contained between adjacent layersof the roll, as set forth.
